FIELD OF INVENTION

The present invention relates to dyed textile articles which have anatural color tone and a natural feeling, deep and fast shades and haveantimicrobial and anti allergic properties. The invention furtherrelates to a method of producing such articles.

BACKGROUND OF THE INVENTION

Use of the natural colors for dyeing i.e. herbal dying is known sincelong. The use of natural colors for dyeing has seen a decline in thepast with the use of more cost effective synthetic dyes which can givevaried colors. However, because of the unique and exquisitecharacteristics of the natural colors they have again been receiving duerecognition in recent years as is shown by general trends towardsfavoring naturalness.

The term “herbal dyeing” means dyeing with plant-derived coloringmaterials. The majority of natural colors are of vegetable origin.However, sometimes colors from animal dyes, such as cochineal and purpleof the ancients (secretions of Murex brandaris, a sea snail) and mineraldyes, such as Berlin (Prussian) blue, is sometimes referred to as herbaldyes.

A great detail of the natural colors applicable to herbal dyeing isavailable in the U.S. Pat. No. 5,880,044, WO2004072182A2 etc. whichinclude coloring matters available from a large variety of plants suchas Carthamustinctorius (safflower), Sophora japonica (Japanese pogadatree), Uncariagambir (gambir), Prunusmume (Japanese apricot), cherrytree, Punicagranatum (pomegranate), Theasinensis (tea),Ternstoremiagymnanthera (evergreen tree), Rubiacordifolia (madder),Caesalpiniasappan (sappan wood), lithospermum, Rhusjavanica (Japanesesumac), Eurya japonica, Artemisia princeps (wormwood),Miscanthussinensis (eulalia), Chrysanthemum morifolium var. sinense(Chinese chrysanthemum) etc. Further, there are several disclosureswhere use of the microorganisms such as fungi, algae has been proposedas a dyestuff.

Japanese Patent Kokai Publication No. 132886/1989 describes a method ofdyeing a textile article which comprises dispersing a microfine powderof quartz porphyry in a water-soluble acrylic resin solution, pouringthe dispersion in hot water, adding a plant extract and a dyestuffthereto, dipping a substrate textile product in the resulting dye bathand carrying out the usual after-treatments such as soaping and drying.

In the conventional herbal dyeing the process is not only complicatedbut has inferior dye reception and color fastness, particularly in thecase of cotton and linen, resulting in the fact that the uniquecharacteristic of the coloring substance is not lasting and this hasbeen the greatest disadvantage of herbal dyeing.

The present invention has been developed, against the above background,to provide a dyed textile article having the natural and unique hue andfeeling and having antimicrobial and anti-allergic activities.

The present invention also relates to dyed textile articles havinghealing properties wherein the raw fibre of the textile article is dyedwith the herbal extract and is stuffed between the layers of theherbally dyed textile articles in the desired shapes.

Ayurveda uses various methods and material to heal. One of the commonmaterial that is used for healing is herbs. Herbs as name signifies areof plant kingdom. Stem, leaves, bark, root, fruit, flower are usedexternally or internally as properties and requirement. Some herbsthrough aroma, others through intake or touch, help in healing. Ayurvedaworks on the principle of enhancing and nourishing natural healingpowers. It supports the maintenance of natural health as well curingthrough illnesses. Illness could be mental or physical illness.

Various traditional herbs are known for healing through touch, smell areused for dying, mixing with cotton, wool and stuffing in clothes(quilting), pillows, mattresses and clothes to support health andhealing for normal health conditions.

Thus one aim of this invention is to support and disseminate the healingthrough the use of Ayurveda in modern societies where the true benefitsof Ayurveda have been long forgotten and the life is filled withchemical products either during the healthy times or during the timewhen one is sick.

Another aim of the invention is to imbibe the benefits of Ayurveda inthe daily life in more effective and simple ways. For example, our skinhas a property to absorb and we in the usual manner try to coat it withchemicals which may be harmful. In one of the embodiments of theinvention, the cotton yarn dyed and stuffed with the herbal extract canbe a good option for healthy living conditions.

SUMMARY OF THE INVENTION

The dyed textile article according to the present invention is preparedusing organic cotton yarn, wherein the raw fibre, yarn and the resultingfabric is dyed and mixed with the predetermined herb to support aparticular health or health conditions.

In another embodiment of the invention, the herbs are blended in theyarn itself as compared to the option of dyeing the textile article,since herbs and their extracts are lost through frequent washings whereas stuffed and blended yarns can have a higher potency through variousmethods like wetting, infusion of steam etc.

In yet another embodiment of the invention, the textile article isprepared by carefully inserting the raw fibre commingled with the herbalextract, between the layers of textile articles already dyed with theherbal extract. The herbal extracts are blended and stuffed in the fibreyarn as compared to the option of dyeing the textile article. In sucharticles, higher potency of the effects of herbs can be achieved throughvarious methods like wetting, steaming etc. Further, the loss of theherbal extracts are reduced as compared to the herbal dyed textilearticles, in these stuffed articles as hereinbefore described, since theherbal extracts are intermingled with the fibre yarn and the loss of theherbal extracts are greatly reduced during frequent washing/drying ofthe textile article.

The present invention also provides for the method of producing suchdyed textile articles wherein the article to be dyed is put in a bathhaving the extract of the dye, which has been prepared by grinding thesaid herb. Further, the present invention also provides for the methodof producing such textile articles wherein the herbs are blended andstuffed in the yarn so that the yarn retains the properties of herb evenafter several washings.

DETAILED DESCRIPTION OF THE INVENTION

The dyed textile article according to the invention can be any and allthe raw fibers, yarns woven fabrics, knitted fabrics, nonwoven fabricsetc. The raw materials for such textile articles are not limited to butinclude cotton, linen, wool, silk etc. However, the invention laysemphasis on the cotton yarn which can be dyed, blended with the and alsostuffed with the herbs.

In accordance with the present invention, raw fibre, the yarn or thearticle to be dyed is bleached, pretreated and then contacted with apre-treating bath. Bleaching is done with natural components like lemonwater, reetha or vinegar in the ratio of 1/20 (bleaching agent/weight ofcloth).

The bath ratio for pretreatment is about 10 to 100 times (particularlyabout 20 to 60 times) based on the weight of the textile article. Thebath temperature is about 50° to 95° C. Preferably between 55° C. to 70°C., and the treating time is about 2 hrs. The concentration of tannicacid is usually about 5% by weight based on the weight of the textileproduct, although the range is not exclusive.

After performing the acid pre-treatment the textile article is contactedwith a mordant bath containing alumina or sea salt for mordanting. Theprocess of mordanting is very important and unless it is carried out,both dyeing affinity and fastness of color will not be upto the mark inthe next dyeing stage.

Sea salt is most commonly used mordant because some herbs like turmericchanges color with alumina and wherever the change in color is required,alumina is used. After bleaching the cloth, the mordanting is done bymixing the mordant in 1/20 ratio (mordant/water) in normal water whiledipping the cloth in mixture for 1 hour.

The mordant bath ratio is about 1:10 to 1:100 (particularly 1:20 to1:60). The bath temperature may range from ordinary temperature toboiling temperature, the treating time is about 10 minutes to 1 hour,and the concentration of the alumina mordant is usually about 3 to 15%by weight, as aluminum ion, although these ranges are not critical

After said pre-treatment and mordanting, the textile article is dyed bycontacting it with a dye bath containing an extract of the desired herbhaving the desired properties. It is important to note that the dyeingshould not precede the acid treatment and mordanting. If mordanting isperformed after dyeing, the desired effect will not be upto the mark.Various formulations for herbal dyes are given below:

Formulation for Yellow Color:

-   -   50%-100% of turmeric extract/wt. of fabric. The turmeric extract        is useful for various skin and liver disorders. The extract can        be utilised in different ratios depending on the requirements.

Formulation for Red Color:

50%-100% of the extract of Rattan Jyot/wt. of fabric. If pink color isrequired, the herb is used in moderation. The extract of this herb isuseful in skin diseases and as a blood purifying agent.

Formulation of Green Color:

-   -   50%-100% of the extract of Neem/wt. of fabric. The extract of        this herb is useful for skin and acts as an antiseptic.    -   50%-100% of the extract of tulsi/wt. fabric. The extract of this        herb is useful for cough and cold and it also acts as an        anti-viral agent.    -   Both of these herbs can also be used in equal proportions to        have effects of both the herbs.

Formulation for Brown Color:

-   -   50%-100% of extract of Ajwain/wt. of fabric. The extract of this        herb is useful in cough, indigestion and liver problems.

By combination of the above colors, many other shades/colors can beobtained. Further many other extracts from different herbs can beutilised for getting a particular color.

The required dye is extracted from the herbs by soaking the herbs inwater wherein the quantity of water is about 15 to 20 times the wt. ofherbs. The solution is boiled at 90° C. for about 1.5 hrs-2 hrs. Thesolution thus prepared is kept overnight. It is then strained throughcloth to avoid unwanted dyes & bigger particles of herbs or any otherparticles. The strained solution is now ready as herbal dye solution. Inpreparing dye solution of turmeric the method is same as above but thetemperature should be maintained at 60° C.

The bath ratio for dyeing reaction is generally about 10-100 times andthe bath temperature is about 50 to 95° C. The treating time isgenerally kept about minimum of 30 minutes to about a maximum of 180minutes. The concentration of the dye can be selected according to thetype of the article, type of the herb and also the size of the articleto be dyed.

After the dyeing process is completed, the article is subjected to thestandard after treatment such as cleaning, washing, rinsing and drying.The resulting textile article is thus a herbal dyed article with aherbal healing quality. It is to be noted that no soap is used forcleaning. However, the article is rinsed with water at high temperaturesto obtain proper sanitization.

The dyeing of the textile article with the herbal extract having anactive ingredient, imparts to the textile the healing properties such asanti allergic properties, antimicrobial properties etc.

Thus the textile article or the further articles made of these textilearticles can be used for various healing purposes.

In one of the embodiment aroma of some herbs like jasmine, tulsi,sehdei, sandal, devdar is being utilized for producing the textilearticles.

In one of the further embodiments of the invention, the wearable clothessuch as diapers etc. used by the healthy infants as well as adultshaving some medical conditions are made with the raw fibre dyed with theherbal extract and stuffed in between the layers of the textile article.Further, customized clothing for particular health conditions can beprepared with the appropriate herbs.

In yet another embodiment of the invention, the gynecological problemscan be treated using the textile articles stuffed with the extract ofthe particular herbs.

In yet another embodiment of the invention, the pillows, mattresses,breast pads, quilts, napkins etc. are stuffed with organic cotton fibreor any other raw textile fibre which are processed and dyed with herbswhich helps in various health conditions and helps maintain healthylife.
